TEXT II
Is There Life On Other Planets?
The ultimate goal of NASA's exoplanet program is to find
unmistakable signs of current life on a planet beyond Earth.
How soon that can happen depends on two unknowns: the
prevalence of life in the galaxy and how lucky we get as we
5 take those first, tentative, exploratory steps.
Our early planet finding missions, such as NASA’s Kepler
and its extended incarnation, K2, or the James Webb Space
Telescope, could yield bare bones evidence of the
potentially habitable worlds. James Webb, designed in part
10 to investigate gas giants and super-Earths, might find an
outsized version of our planet. NASA's Nancy Grace Roman
Space Telescope or the Wide-Field Infrared Survey
Telescope, could zero in on a distant planet’s reflected light
to detect the signatures of oxygen, water vapor, or some
15 other powerful indication of possible life.
But unless we get lucky, the search for signs of life could
take decades. Discovering another blue-white marble hidden
in the star field, like a sand grain on the beach, will probably
require an even larger imaging telescope. Designs are
20 already underway for that next-generation planet finder, to
be sent aloft in the 2030s or 2040s.
MIT physics professor Sara Seager looks for possible
chemical combinations that could signal the presence of
alien life. She and her biochemistry colleagues first focused
25 on the six main elements associated with life on Earth:
carbon, nitrogen, oxygen, phosphorous, sulfur and
hydrogen.
“We’re going to have so few planets, we have to get lucky,”
Seager said. “I don’t want to miss anything. I don’t want to
30 miss it because we weren’t smart enough to think of some
molecule.”

Resolução comentada
K2 é uma missão que deu continuidade ao que o Kepler iniciou.
'Extended incarnation' indica que o K2 é uma versão estendida da missão Kepler, que prosseguiu com o trabalho dela de outra forma.
Análise das alternativas
A) Errada: o texto não diz que o K2 faz 'tudo e mais'. C) Errada: não se fala em descontinuação e recomeço do processo. D) Errada: 'incarnation' aqui não significa reencarnação de vidas.
